零切迹颈前路椎间融合固定系统在颈前路融合术中的初步应用

The primary clinical application of Zero-p anterior cervical intervertebral fusion system for cervical intervertebral fusion

目的探讨零切迹颈前路椎间融合固定系统(Zero-p ACIF)在颈椎前路融合术中的应用效果。方法 2009-12-2010-10,对24例(26节段)颈椎疾病患者行前路椎间零切迹椎间融合固定系统内固定,其中颈椎外伤性椎间盘突出、不稳7例,颈椎间盘疾患17例,其中双节段2例。结果24例患者随访12～20个月,平均随访14个月,JOA评分由术前平均8.6分上升到末次随访时15.2分,术后X线片与末次X线片提示椎间高度无丢失,内固定无松动。结论 Zero-p ACIF有较优异的材料和力学性能,能有效维持融合椎间高度,对椎前组织无影响,是一种新的颈前路融合手段。

Objective To revaluate the clinical effect of zero-p anterior cervical intervertebral fusion system（zero-p ACIF）for cervical anterior intervertebral fusion.Method From 2009.12 to 2010.10,24cases of patients were treated surgically by zero-p ACIF.22 cases of single-level,2cases of two-level,incloud 7 cases cervical injury and 17 cases cervical spondylotic myelopathy.Result All cases obtained follow up with average of 14months（range 12 to 20 months）,all cases have no postoperative dysphagia and tardive esophageal fistula.The disc height were achieved in final follow-up respectively.Place of intervertebral fusion system has no change or loose.Conclusion Zero-p ACIF has more excellent material and mechanical properties,can effectively maintain the fusion cage height and no effect on the prevertebral tissue.It is a new means of anterior cervical fusion.
